Is it rude to bring DSLR to wedding?

Wheatfield, you are an azz in every single thread. Why someone would hire a jack wad like you to do anything is beyond me. Yeah, and real photographers wouldn't consider a 'wedding photographer' like you a pro either. I hope you stay out of their way when you see a real photo shoot. I am sure you'd be like 'hey, you know what camera I shoot weddings with" and they would tell you to get a real job.
